使用Tiled编辑地图
- 每个图层仅仅能放一种瓦片
- 瓦片的大小最好是32*32的倍数
- 对象层里面设置路径的坐标
- 主程序中获取对象层中的坐标，做对应的操作
设置口袋精灵类：
Monster.h
#include "cocos2d.h"USING_NS_CC;class Monster : public Sprite
{
public:virtual bool init(Vector<Node*> points);static Monster* create(Vector<Node*> points);//用于获取对象层的坐标Vector<Node*> p;Vector<Node*>::iterator start;//精灵Sprite *s;//依照路径移动void moveByPath();//种类随机数int ranNum;};
Monster.cpp
#include "Monster.h"Monster* Monster::create(Vector<Node*> points)
{auto monster = new Monster();monster->init(points);monster->autorelease();return monster;
}bool Monster::init(Vector<Node*> points)
{Sprite::init();//设置随机数，控制出场精灵种类srand(time(NULL));ranNum = rand()%5;p = points;start = p.begin();switch (ranNum){case 0 :{s = Sprite::create("1.png");break;}case 1:{s = Sprite::create("2.png");break;}case 2:{s = Sprite::create("3.png");break;}case 3:{s = Sprite::create("4.png");break;}case 4:{s = Sprite::create("5.png");break;}}s->setPosition((*start)->getPosition());addChild(s);return true;
}//沿着路径移动
void Monster::moveByPath(){++start;if(start == p.end()){s->removeFromParent();}else{Point a = Point((*start)->getPosition());s->runAction(Sequence::create(MoveTo::create(2,a),CallFuncN::create(CC_CALLBACK_0(Monster::moveByPath,this)),NULL));}
}
主场景类
HelloWorldScene.h
#ifndef __HELLOWORLD_SCENE_H__
#define __HELLOWORLD_SCENE_H__#include "cocos2d.h"
#include "Monster.h"USING_NS_CC;class HelloWorld : public cocos2d::LayerColor
{

HelloWorldScene.cpp
#include "HelloWorldScene.h"USING_NS_CC;Scene* HelloWorld::createScene()
{auto scene = Scene::createWithPhysics();auto layer = HelloWorld::create();scene->getPhysicsWorld()->setDebugDrawMask(PhysicsWorld::DEBUGDRAW_ALL);scene->getPhysicsWorld()->setGravity(Point(0,-1000));scene->addChild(layer);return scene;
}// on "init" you need to initialize your instance
bool HelloWorld::init()
{//// 1. super init firstif ( !LayerColor::initWithColor(Color4B(255,255,255,255)) ){return false;}Size visibleSize = Director::getInstance()->getVisibleSize();Point origin = Director::getInstance()->getVisibleOrigin();//加入物理边界auto body = PhysicsBody::createEdgeBox(visibleSize,PHYSICSBODY_MATERIAL_DEFAULT,3); auto node = Node::create();node->setPhysicsBody(body);node->setPosition(visibleSize.width/2,visibleSize.height/2);addChild(node);//加入地图文件auto map = TMXTiledMap::create("pokamon.tmx");map->setPosition(200,0);addChild(map);//获得对象层中的坐标,存在向量里TMXObjectGroup* objectGroup = map->getObjectGroup("monster");ValueVector object = objectGroup->getObjects();for (ValueVector::iterator it = object.begin(); it != object.end(); it++) {Value obj = *it;ValueMap m = obj.asValueMap();auto node = Node::create();node->setPosition(m.at("x").asFloat()+200,m.at("y").asFloat());points.pushBack(node);}//重置时间resetTime();//开启计时器scheduleUpdate();return true;
}void HelloWorld::update(float dt)
{++oldTime;if (oldTime == curTime){resetTime();addMonster();}
}void HelloWorld::resetTime()
{oldTime = 0;curTime = 40;
}void HelloWorld::addMonster()
{auto hero = Monster::create(points);hero->moveByPath();addChild(hero);
}void HelloWorld::menuCloseCallback(Ref* pSender)
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8) || (CC_TARGET_PLATFORM == CC_PLATFORM_WINRT)MessageBox("You pressed the close button. Windows Store Apps do not implement a close button.","Alert");return;
#endifDirector::getInstance()->end();#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)exit(0);
#endif
}
效果：
